To install products , you need acces to the Control Panel and import directory.
My Zope hosting company doesn't give access to these functions. (for security reasons I guess)
On my home computer I also installed Zope ; could I install a product ( Zubb for example) , go to where the files have been installed  and then copy the content of these files on the Zope hosting company server ?
Would this work ? ( As you have probably already understood, I am quite new in Zope :-)
Thanks for your answer.
